What decides between GRP v1.28 and v1.22

(moderation:
When I started running a pair of GTX 980's they started running only v1.22 until I put the newest drivers on them and then they switched to 1.28
I have had a GTX 660Ti for years but never even knew there was these two versions before but now I see it only runs v1.22 and I updated to the newest drivers the same as the two 980's but that didn't make any difference so it still runs only v1.22
Also on all of my hosts running GPU's here (only) they will have the certain Run Time but the CPU time is only 2 minutes or less that includes the 980's and the two laptops that run off of the AMD APU
BUT on the host with the 660Ti has the expected Run time BUT the CPU time is the same as the run time.
Why would that happen?
https://einsteinathome.org/host/11652712/tasks/4/0 The 660Ti runs here now
https://einsteinathome.org/host/10859996/tasks/0/0 The 660Ti was running on here before that one
The 660Ti also ran on one that now has one of the 980's (for over 7 years)
the v1.28 app is only shipped
)
the v1.28 app is only shipped to cards with Maxwell or newer architecture (CC 5.0 and greater) AND with drivers giving OpenCL 2.0 or greater (for nvidia this was around driver 470 and newer). you need both.
the 660Ti is a Kepler generation card with CC of only 3.0. so it's older than the requirement for the the better 1.28 app.
nvidia runtime and cpu time being roughly equal is totally normal. and a look at your GTX 980 systems, they too follow this behavior. this is just how the nvidia application is, it uses a whole CPU per task. the AMD application uses less CPU, and hence has less cpu time recorded. there's nothing to worry about there.
